Unfortunately we had to pull the functionality to convert BigWig and BigBed files from the Convert Wizard due to visualization issues with this data type. We forgot to remove these file types from the dropdown menu when we removed support for the data. So any BigWig or BigBed files added to the Convert Wizard will produce the error you have seen.

Once we are able to add back in support for these file types we will let you know. Sorry of the inconvenience.
